I'm all about women enjoying themselves and embracing their beauty at no matter whatage, but someone needs to tell Kris Jenner to stop. It's enough already. Come on, 58 years old is not the new 18 years old. Or even 28.

The unapologetically flashy momager was snapped in the audience at future son-in-law Kanye West's Long Island concert the other night wearing a sequined black minidress and thigh-high boots that made for an outfit that was (unsurprisingly) a smidge too short, a bit too flashy, a hint too tight, and a whole lot of trying way too hard.

See what I mean? It's not like the woman doesn't know how to dress appropriately or in a polished, classy way! She totally does! But for some reason, the grandmother of three still seems hell-bent on "keeping up" with her daughters from time to time. And it bears noting that even Kim and Kourtney, who accompanied mom to the concert, were dressed down for the show. Thus, Kris stood out even more like a sore thumb -- not in a good way ...

Don't get me wrong: She deserves to live it up, and you gotta love how much she's enjoying cheering on Yeezy, but couldn't she do that without crossing into Pretty Woman territory? There's glam, and then there's cringe-worthy. And no matter the occasion, Kris's latest look is definitely erring toward the latter.
